Three new species of comb-clawed beetles редко пунктированными междурядьями надкрылий, of the tribe Alleculini (Tenebrionidae: Alleculinae) но отличается небольшими размерами (длина тела are decribed. Gonodera baygushevae Nabozhenko et 6.6 мм, в то время как другие Gonodera Mulsant, 1856 c I. Chigray, sp. n. (Eocene Baltic amber) is similar to extant минимальной длиной 8 мм), удлиненной пунктировкой Gonodera rufoaenea Reitter, 1900 by very finely and sparsely головы, примерно равной шириной основания punctated elytral intertriae, but differs in the small size of надкрылий и переднеспинки и 6 зубчиками на коготках body (6.6 mm, while other species of Gonodera Mulsant, (другие виды Gonodera с 7 зубчиками). Gonodera kasatkini 1856 have a minimal length of 8 mm), elongate punctation Nabozhenko, sp. n. (рецентный вид, Ливан) относится к of head, subequal width of elytral and pronotal bases and видам с почти равной длиной антенномеров 3 и 4 самца six teeth on both clavae (other Gonodera have seven teeth). и отличается от всех представителей этой группы Gonodera kasatkini Nabozhenko, sp. n. (extant, Lebanon) отсутствием базального вдавления переднеспинки belongs to the species-group with subequal antennomeres 3 и сильно вдавленным в основании 5 междурядьем. and 4 of male and differs from all other species of this Mycetochara (s. str.) abdurakhmanovi Nabozhenko, sp. n. group in the absence of basal impression on pronotal (рецентный вид, Ливан) отличается от всех disc and strongly depressed 5th elytral interstria at base. западнопалеарктических видов подрода комбинацией Mycetochara (s. str.) abdurakhmanovi Nabozhenko, sp. n. красного проторакса и черных надкрылий, крупным (extant, Lebanon) differs from all Western Palaearctic продольно-овальным вдавлением в передней половине Mycetochara s. str. in the combination of red protorax переднеспинки и 6 длинными ланцетовидными with black elytra, large longitudinal oval impression in the шипиками на апикальной доле эдеагуса. Приведены middle of anterior half of pronotum and eight long lanceolate новые данные по распространению Isomira (s. str.) spines on apical lobe of aedeagus. New distributional data antennalis Reitter, 1884 (первое указание для Ливана), for Isomira (s. str.) antennalis Reitter, 1884 (the first record Mycetochara (Ernocharis) ruficollis Baudi di Selve, 1877 и for Lebanon), Mycetochara (Ernocharis) ruficollis Baudi di Hymenalia ehdenica Novák, 2017 в Ливане. Selve, 1877 and Hymenalia ehdenica Novák, 2017 are given. Резюме. Описано 3 новых вида пыльцеедов Alleculinae is one of the largest subfamily in the трибы Alleculini (Tenebrionidae: Alleculinae). world within the family Tenebrionidae with 188 extant Gonodera baygushevae Nabozhenko et I. Chigray, sp. n. and 6 extinct genera [Bousquet et al., 2015]. This group is (эоценовый балтийский янтарь) похож на рецентный known since the Mesozoic Era. The earliest comb-clawed вид Gonodera rufoaenea Reitter, 1900 очень тонко и Cistelites insignis with unclear taxonomic position has DOI: 10.23885/181433262018142-171176 172 M.V. Nabozhenko, I.A. Chigray been described from the Lower Jurassic of Switzerland of the University of Hamburg, Germany. The amber piece (Schambelen, Insektenmergel formation, Aargau, was hand-polished allowing improved views of the included Switzerland) [Heer, 1865]. The oldest accurate species specimen, and was not subjected to any additional fixation. of Alleculinae was described from the Upper Jurassic We also studied the material on extant comb-clawed of the Kara-Tau (Karabastau Formation, Callovian, beetles collected by Dr Denis Kasatkin in Lebanon in Kazakhstan) [Medvedev, 1969]. Other Mesozoic species 2018, which will be deposited in Zoological Institute of the of the subfamily are known from the Lower Cretaceous Russian Academy of Sciences (ZIN, St Petersburg, Russia) of Yixian (Yixian formation, Liaoning Province, China) and partly in the private collection of M.V. Nabozhenko [Nabozhenko et al., 2015; Chang et al., 2016] and (CN, Rostov-on-Don, Russia). Upper Cretaceous of Sakhalin (Mgrach, Santonian Stage, Sakhalin, Russia) [Heer, 1878]. Most fossil taxa Tribe Alleculini of Alleculinae were found in Eocene Baltic amber Subtribe Gonoderina (eight taxa) and the Florissant Formation (three taxa, Gonodera baygushevae Nabozhenko et I. Chigray, sp. n. Chadronian, Colorado, USA). (Figs 1, 2) Baltic amber contains species of the extint genus Mycetocharoides Schaufuss, 1888 and the extant genera Material. Holotype, ♀, single incusion, with label: “GPIH 4989, coll. Gröhn 0026 Gonodera baygushevae HT Nabozhenko 2018. The holotype Isomira Mulsant, 1856, Mycetochara Berthold, 1827, is deposited in GPIH – Geologisch-Paläontologische Museum Universität Hymenalia Mulsant, 1856, Cteniopus Solier, 1835 and Hamburg, now: CeNak (Centrum of Natural History). In the Museum of Cteniopinus Seidlitz, 1896. The last four genera are based on GPIH the collection of Mr. Carsten Gröhn is separately deposited (4989 is the lost material listed in Klebs [1910]. The genusIsomira the museum number, 0026 is the number of the collection of C. Gröhn). Description. Body length 6.6 mm. Body moderately (Alleculini: Gonoderina) dominates among Baltic amber robust, glabrous, shiny. Head widest at eye level, with coarse and samples and is represented by 2–3 species (including fossil dense (puncture diameter subequal to interpuncture distance) Isomira avula Seidlitz, 1896) from the Eastern Palaearctic punctation, punctures around frons elongate, sometimes merged, species-groups (unpublished data of M.V. Nabozhenko frontoclypeus with coarser and denser punctation of elongate with co-authors). Below we describe the first member of the punctures, frons with sparser punctation of round punctures genus Gonodera Mulsant, 1856 from Baltic amber. Extant (puncture diameter 1.5–2 times shorter than interpuncture species of this genus are distributed in Southern Europe, distance). Apical maxillar palpomeres weakly triangular, with strongly oblique apical margin. Eyes large, reniform, convex, Turkey, the Caucasus and Iran [Novák, Pettersson, 2008; transverse (height 2.3 times as long as transverse length), 1.5 times Novák, 2011]. One fossil Gonodera was described from the as long as interocular space of frons. Antennae comparatively short, late Eocene Florissant Formation of USA [Wickham, 1913]. with 2 apical antennomeres extended beyond base of pronotum, So, this group had a significantly wider range in the Eocene antennomere 3 much shorter than antennomere 4. Length(width) if Wickham correctly determined the genus. of 2–11 antennomeres: 10(8), 22.5(10), 36(13), 37(13.5), 38(11), Below we also describe several species of alleculine 37.5(17), 35(17.5), 36.5(17), 35.5(16.5), 45(15.5). beetles of the tribe Alleculini from Lebanon. Comb-clawed Pronotum transverse, nearly 1.3 times as wide as long, bell- beetles of the Middle East are poorly studied, many genera shaped, widest at base; anterior margin widely rounded; base bisinuate, weakly rounded in middle; lateral margins weakly with numerous old species need revision. Important rounded in basal half and strongly rounded converging to anterior revisions on Alleculinae of this region were published in margin. Anterior angles not visible, widely rounded, posterior the 20th Century on the genus Gonodera [Mařan, 1944], ones acute, narrowly rounded at apex. Base narrowly beaded, the tribe Cteniopodini [Ogloblin, Znojko, 1950], the genus anterior margin beaded near anterior angles, lateral margins with Isomira Mulsant, 1856 of the former USSR and ajacent very narrow, inconspicuous beading. Punctation of pronotum countries [Dubrovina, 1982; Yablokov-Khnzoryan, 1983]. coarse and dense (puncture diameter subequal to interpuncture The most important contribution in the 21th Century distance), punctures round.
